Background: Encephalopathy can occur from a non-fatal toxic drug event (overdose) which results in a partial or complete loss of oxygen to the brain, or due to long-term substance use issues. It can be categorized as a non-traumatic acquired brain injury or toxic encephalopathy. In the context of the drug toxicity crisis in British Columbia (BC), Canada, measuring the co-occurrence of encephalopathy and drug toxicity is challenging due to lack of standardized screening. We aimed to estimate the prevalence of encephalopathy among people who experienced a toxic drug event and examine the association between toxic drug events and encephalopathy. Methods: Using a 20% random sample of BC residents from administrative health data, we conducted a cross-sectional analysis. Toxic drug events were identified using the BC Provincial Overdose Cohort definition and encephalopathy was identified using ICD codes from hospitalization, emergency department, and primary care records between January 1st 2015 and December 31st 2019. Unadjusted and adjusted log-binomial regression models were employed to estimate the risk of encephalopathy among people who had a toxic drug event compared to people who did not experience a toxic drug event. Results: Among people with encephalopathy, 14.6% (n = 54) had one or more drug toxicity events between 2015 and 2019. After adjusting for sex, age, and mental illness, people who experienced drug toxicity were 15.3 times (95% CI = 11.3, 20.7) more likely to have encephalopathy compared to people who did not experience a drug toxicity event. People who were 40 years and older, male, and had a mental illness were at increased risk of encephalopathy. Conclusions: There is a need for collaboration between community members, health care providers, and key stakeholders to develop a standardized approach to define, screen, and detect neurocognitive injury related to drug toxicity.

Objective: Significant barriers exist for youth in obtaining mental health services. These barriers are exacerbated by growing demand, attributed partially to children and adolescents who have repeat hospital admissions. The purpose of this study was to identify demographic, socioeconomic and clinical predictors of readmission to inpatient psychiatric services in New Brunswick, Canada. Method: Key demographic, support and clinical predictors of readmission were identified. The New Brunswick Discharge Abstract Database (DAD) was used to compile a cohort of all children and adolescents ages 3–19 years with psychiatric hospital admissions between 1 April 2003 and 31 March 2014 (N = 3825). Primary analyses consisted of Kaplan–Meier survival methods with log‐rank tests to assess time‐to‐readmission variability, and Cox regression to identify significant predictors of readmission. Results: In total, 27.8% of admitted children and adolescents experienced at least one readmission within the 10‐year period, with 57.3% readmitted to hospital within 90 days following discharge. Bivariate results indicated that male, upper‐middle socioeconomic status (SES) youths aged 11–15 years from nonrural communities were most likely to be readmitted. Notable predictors of increased readmission likelihood were older age, being male, higher SES, referral to care by medical practitioner, discharge to another health facility, psychosis, and previous psychiatric admission. Conclusion: A significant portion of the variance in readmission was accounted for by youth demographic characteristics (i.e. age, SES, geographic location) and various support structures, including referrals to inpatient care and aftercare support services. Key Practitioner Message: Readmission to inpatient psychiatric care among youth is affected by a number of multifaceted risk factors across individual, environmental and clinical domains.This study used provincial population‐scale longitudinal administrative data to demonstrate the influence of various individual and demographic factors on likelihood of readmission, which is notably absent from the majority of studies that make use of smaller, short‐term data samples.Ensuring that multiple factors outside of the clinical context are considered when examining readmission among youth may contribute to a more thorough understanding of youth hospitalization patterns.

The purpose of this project was to examine the emotional health and well-being of Canadian caregivers of persons with significant mental health or addictions problems. We assessed the emotional health of caregivers by care-receiver condition type (i.e. mental health or addictions vs. physical or other health problems), levels of caregiver stress and methods particularly for reducing stress among caregivers of persons with mental health or addictions disorders. Weighted cross-sectional data from the 2012 General Social Survey (Caregiving and Care Receiving) were modelled using weighted descriptive and logistic regression analyses to examine levels of stress and the emotional health and well-being of caregivers by care-receiver condition type. Caregivers of persons with mental health or addictions problems were more likely to report that caregiving was very stressful and that they felt depressed, tired, worried or anxious, overwhelmed; lonely or isolated; short-tempered or irritable; and resentful because of their caregiving responsibilities. The results of this study suggest that mental health and addictions caregivers may experience disparate stressors and require varying services and supports relative to caregivers of persons with physical or other health conditions.
